CHP Officer Ming Hsu said Kardashian was pulled over at about 1 p.m. on the 101 Freeway near the Van Nuys Boulevard exit. Three other cars apparently driven by paparazzi were also stopped, although two of them left the scene before an officer was able to talk to the photographers, according to a news release.

The third photographer, Juliano A. Goncalves, pulled around Kardashian's vehicle and started taking pictures. He was cited for speeding and stopping in a nonemergency situation, Hsu said.

An email sent to a representative for Kardashian was not immediately returned. Attempts to reach Goncalves for comment were unsuccessful.

Kardashian, 33, who stars along with her family in the reality series "Keeping Up With the Kardashians," has generally had a good relationship with the paparazzi. Her fiance, rapper Kanye West, however, has had several skirmishes with celebrity photographers.

West has pleaded not guilty in a misdemeanor case in which he's accused of fighting with a paparazzo and attempting to take his camera.
